2012 Table of Detected Contaminants For Chamberlain (EPA ID 0086)
Terms and abbreviations used in this table:
* Maximum Contaminant Level Goal(MCLG): the level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
* Maximum Contaminant Level(MCL): the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.
* Action Level(AL): the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow. For Lead and Copper, 90% of the samples must be below the AL.
* Treatment Technique(TT): A required process intended to reduce the level of a contaminant in drinking water. For turbidity, 95% of samples must be less than 0.3 NTU
Units:
*MFL: million fibers per liter
*pCi/l: picocuries per liter(a measure of radioactivity)
*ppt: parts per trillion, or nanograms per liter
*mrem/year: millirems per year(a measure of radiation absorbed by the body)
*ppm: parts per million, or milligrams per liter(mg/l)
*ppq: parts per quadrillion, or picograms per liter
*NTU: Nephelometric Turbidity Units
*ppb: parts per billion, or micrograms per liter(ug/l)
*pspm: positive samples per month
